Title: Improvements relating to bobbin-winding machines
IPC: B65H67/06
Filed: 1957-02-25
Abstract: 814,850. Delivering filled bobbins to pinboards. ROSENKRANZ, C. G., HALSTENBACH, H., and PLUTTE, A., [trading as HALSTENBACH & CO.]. Feb 25, 1957 [April 12, 1956], No. 6261/57. Class 120(3) In means for delivering filled bobbins to pinboards in a winding machine, under each winding position is a receiving trough which tilts downwardly when a wound bobbin falls into it and conducts the bobbin to the board which is given a reciprocating movement and, during at least part of the movement, a further movement in a direction inclined to the direction of the reciprocating movement is superposed. In Fig. 1, for each group of winding position Sp there is a member B which slides under the control of the winding apparatus to allow a wound bobbin to fall into a trough 12, one for each position which is carried by pivoted arms 11, and can descend, under the weight of the bobbin, in guides 13. The front of the trough has flaps 18 which are opened or shut as an arm, on the shaft on which they are mounted, engages stops 191, 192, the flaps being held in open or shut position by a spring moving over centres. The bobbins are deposited on pins in boards, a number of which are removably carried by a frame 24 on a plate 3. Vacant pins are brought into position by imparting to the plate the successive movements indicated by the arrows in Fig. 10. The first two movements of each cycle of three is the resultant of two superimposed movements at right angles to which the plate is subjected, and the third a movement in one direction. To this end, the plate is movable on rails 41, Fig. 5, in the direction of the arrow a: together with these rails it can also move according to the arrow b along guide-bars 43. These movement are initiated as each winding is completed and the winding mechanism pulls a cable 44 to rotate a disc 45 against a spring 47. This rotation is transmitted to a ratchet disc having three positions at intervals of 120 degrees, and thus to a shaft carrying a cam 50 and a cam-race 51. The former has three projections two of which, the other being shorter and inoperative, engage one end of a pivoted lever 53 which at the other end engages a rack 31 on the plate 3: the cam-race is engaged by a member 58 anchored at its other end. The pin, arranged on each board in staggered relationship in three rows, project at an angle of less than 85 degrees so that the bobbins do not fall off when the boards are hung up: the handles of the frame are in line with the centre of gravity when loaded for convenience in carrying. When the trough has deposited a bobbin, it returns as a chain &c. 16 is actuated by the winding apparatus, passing beneath a pivoted member c to avoid damage to the bobbins.

Title: Improvements in or relating to apparatus for the determination and/or control of the proportions of the constituents in a fluid mixture of emulsion
Inventor: WARD RICHARD
IPC: G01N21/43
Filed: 1966-02-12
Abstract: 1,116,560. Photo-electric refractometers. GULLICK, Ltd. Jan. 19, 1967 [Feb. 12, 1966], No.6286/66. Heading G1A. The proportion of the constituents in a fluid mixture or emulsion e.g. of oil in water are determined by two photo-electric refractometers, one investigating changes in refractive index of the test fluid and another changes in refractive index of a reference fluid which contains the constituents in the required proportions. Deviations of the refractive index of the test fluid from that of the reference fluid are measured by a Wheatstone bridge circuit and the out-of-balance current or voltage may be used to control the proportions of the constituents when a continuous flow of test fluid is being monitored. The apparatus of Fig. 2 shows a light source 17 from which beams are directed by lenses 19 and prisms 18, into long glass prisms 12 and 13. Prisms 18 may be attached to prisms 12, 13. Prism 12 is immersed in the reference fluid contained in chamber 14a, which is itself contained in the test fluid flowing through the chamber 14 from inlet 15 to outlet 16. Photo-cells 10, 11, which may be photo-resistive or photovoltaic, are connected in a Wheatstone bridge circuit Fig. 3 (not shown) supplied by a stabilized source. The microammeter of the bridge circuit, may be calibrated in refractive index or the relative proportion of one constituent in the fluid e.g. the amount of oil in the oil/water emulsion. Alternative circuits are described, one provided with checking facilities for compensating for changes in lamp brightness Fig. 4 (not shown) and one for reducing the errors due to temperature differences between the reference and test fluids Fig. 5 (not shown), in which case thermistors immersed in the fluids are added to the apparatus of Fig. 1. Single test samples introduced through tap 24 may be measured instead of a continuous flow.

Abstract: 434,651. Watches. MARTI, F., 137, Rue du Parc, La Chaux-de-Fonds, Switzerland. March 4, 1935, No. 6788. Convention date, May 30, 1934. [Class 139] The winding and setting crown of a watch is axially and rotatably slidable on the pendant and loosely engages an element fixed to the winding and setting spindle, for example, by a pin-and-slot connection. The crown 4 is rigid with a ring 3 rotatable and axially slidable on the pendant 2 fixed to the case 1. Screwed on the winding and setting stem 6 is a member 5 provided with two projections 7 located in slots 8, Fig. 2, in the ring 3 whereby rotary motion is imparted to the stem. Two balls 9 housed in radial holes in the ring 3 are forced by an annular spring 10 into engagement with a cam groove 12 in the pendant to force the ring 3 against the shouldder 11 on the pendant to exclude dust and water. When the crown is pulled out for hand-setting, the balls 9 ride up the sides of the cam groove against the action of spring 10 and the bottom faces of the slots 8 in ring 3 engage the member 5 to move the stem 6 axially. The pin and slot connection 7, 8 thus permits easy rotation of stem 6 even if it is offset relative to the axis of the pendant.

Title: Improvements relating to the formation of silica-alumina slurries adapted for conversion into gel-type catalysts
IPC: B01J21/12
Filed: 1953-03-13
Abstract: A silica alumina slurry suitable for conversion into a gel type catalyst is formed by reacting a mineral acid and an alkali metal aluminate in the presence of hydrated silica gel in aqueous suspension whereby aluminium hydroxide is precipitated on the hydrated silica gel.  In an example, nine tons (1420 gallons) of 50 per cent sodium hydroxide solution were measured out and heated to approximately 100-105 DEG C. and 8.2 tons of bauxite ore concentrate were added thereto; the temperature being brought rapidly to 110-112 DEG C. and then more slowly to 117 DEG C.  Water was then added to dilute the solution to 2860 gallons.  The sodium aluminate thus formed contained approximately 28.5 per cent by weight alumina and 19.5 per cent by weight of sodium oxide.  This solution was stored at at least 75 DEG C. while 1900 lbs. of hydrated silica gel at a pH of 6.4-7.6 were run into a coating tank and 26 gallons of 25 per cent sulphuric acid solution added thereto, thus reducing the pH to approximately 3.  Eighty gallons of the sodium aluminate solution were withdrawn from storage, diluted with 51 gallons of water and the diluted solution run into the hydrated silica gel simultaneously with 140 gallons of 25 per cent. sulphuric acid solution thus raising the pH of the silica gel to 4.0-5.5.  Aluminium trihydrate was precipitated onto the silica gel.  Approximately 10 gallons of sulphuric acid were then added to bring the pH to approximately 4.7. Following ageing for 30 minutes, the slurry was washed and filtered; drying and calcining the slurry leads to a silica-alumina gel catalyst which is suitable for use as a cracking or dehydration catalyst. Specification 626,455 is referred to.

Title: Improvements in the decolorizing and purification of saccharine materials
IPC: C13B20/12
Filed: 1928-03-06
Abstract: 312,705. Wooldridge, H. B., and Clark, P. G. March 6, 1928. Purifying saccharine liquids.-Beet and cane sugar in the form of low grade syrup containing invert sugar, e.g. molasses, are purified particularly for use in the production of a white yeast but also for other purposes. The molasses or sugar liquor is passed as a thin syrup through an ordinary cloth filter press coated with any filter acid, preferably that known as " Celite," " Super Cell " or " Hyflo." The solution is then allowed to percolate through precipitated alumina, the trihydrate or one of the various forms of bauxite, or magnesium hydrate. In the case of many cane syrups it is necessary to defecate the weak syrup by boiling it with weak phosphoric acid and neutralizing with lime water before passing it through the filter. The Provisional Specification states that bauxite may be replaced by other filtering media such as activated carbon or char. Specification 134,607 is referred to.
Patent GB-230861-A (GB)
Title: Improvements in the production of artificial resins
IPC: C08G8/28
Filed: 1925-03-16
Abstract: In the production of such artificial resins as require during their preparation a concentrating or drying, the concentration or drying of the liquid reaction products is carried out by heating them for a short time while in a finely divided state or in thin layers.  Thus the reaction product may be atomized or may be distributed on rollers or endless belts during the heating.  The process is applicable to phenol-aldehyde resins particularly of the "novolak" and "resol" type and impure reagents such as crude cresol or low temperature tars may be employed.  The complete process of producing the resins may be carried out continuously by introducing the reagents to a preheater, such as a heated copper coil, and distributing the mixture as above described with or without a previous passage through a water separator.  The concentrated liquid resin may be employed as it leaves the concentration plant by connecting the latter directly with a further plant such as a paper sizing machine.  The vapours produced during concentrating may be condensed and worked up.

Title: Process an plant for removing sulphur oxides from gases
IPC: C01B17/60
Filed: 1972-02-17
Abstract: 1363164 Sulphur; removing SO2 from gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 17 Feb 1972 [19 Feb 1971] 7373/72 Heading C1A Sulphur is produced from gases containing SO2 by absorbing the SO2 on a solid acceptor, regenerating the SO2 from the acceptor, absorbing the SO2 in a liquid absorbent, regenerating the SO2 from the liquid, and supplying the SO2 to a Claus plant. The solid acceptor may be (a) Cu or Cu oxide on a support of gamma-Al2O3, bauxite, SiO2-Al2O3 or SiO2-MgO, which may be regenerated with a reducing gas, e.g. H2, CO or hydrocarbons, preferably diluted with N2 or steam, or with a gas containing O2, or (b) carbon which is regenerated by heating at 400-600‹ C. with an O2-free gas. The regenerated SO2- containing gas may be cooled to form a condensate, which may be (a) added to the gas to be cooled and additionally to the cooled gas after compression (Fig. 2) or (b) stripped to remove SO2 which is added to the gas to be cooled (Fig. 3). Alternatively, the gas may be quenched with water, part of the quench water being recycled and the rest added to the cooled gas after compression (Fig. 6). The liquid absorbent may be water, N-methyl pyrrolidone, xylidene, dimethylaniline, sulpholane, or sulphinol, and the gas is preferably at 10-60‹ C. and 1-10 atm. pressure. The absorbent may be regenerated indirectly or by direct heating with steam, preferably using a buffer zone of loaded absorbent to ensure a steady stream of SO2. The SO2 is then supplied to the Claus plant mixed with H2S in the ratio 1 : 2. The H2S may be obtained (a) from a separate source (Fig. 1), (b) by catalytic reduction of 2/3 of the SO2 (Fig. 4), or (c) by passing the SO2 together with hydrocarbons, e.g. butane, and a deficiency of O2, to a combustion zone (where some S is also produced) to give the required H2S/SO2 mixture (Fig. 5). In process (b) the reducing agent may be H2, CO, methane, ethane, propane, butane, town, water, or synthesis gas, or the off-gas from catalytic reforming. The catalyst may be sulphided Mo, W, Cr, Co, Ni, Fe or mixtures thereof on a carrier of Al2O3, SiO2, MgO, B2O3, ZrO2 or ThO2, or may be V oxide or Al2O3. The SO2 stream may be divided in two, or a deficiency of reducing gas may be used. The temperature may be at least 180‹ C., preferably 200-650‹ C. The Claus off-gas may be burned with air together with the gas not absorbed in the liquid absorbent, and the combustion gas recycled to be mixed with the initial fine gas in a ratio of 0À02 : 1 to 1 : 1.
